  • Vehicle centre of mass, roll-centre and pitch-centre height estimation 
    Botha, Theunis R.; Els, Pieter Schalk (Inderscience, 2019)
    The location of a vehicle’s centre of mass is an important parameter as it has a determining effect on the dynamics of a vehicle. The height of the vehicle centre of mass from the roll and pitch centres has a large ...
  • Vehicle suspension force and road profile prediction on undulating roads 
    Hamersma, Herman Adendorff; Els, Pieter Schalk (Taylor and Francis, 2021)
    Controllable suspension systems have the capability of changing suspension forces. One control approach is to define a cost function with the aim of optimising either ride comfort or handling. Such controllers are usually ...
  • The viability of refuse-derived fuel as a green household cooking fuel 
    Nwaokocha, Collins N.; Phakatkar, Haribhau G.; Giwa, Solomon Olanrewaju; Layeni, Abayomi T.; Kale, Sandip A. (Blue Eyes Intelligence Engineering and Sciences Publication, 2019-06)
    Rice husk and sawdust are waste generated freely in many developing countries in the cause of rice production and wood processing respectively. This large biomass volume can be useful as an energy resource useful in ...
  • Vibration analysis of a tire in ground contact under varied conditions 
    Karakus, Murat; Cavus, Aydin; Colakoglu, Mehmet (Polish Society of Theoretical and Applied Mechanics, 2017)
    The effect of three different factors, which are inflation pressure, vertical load and coefficient of friction on the natural frequencies of a tire (175/70 R13) has been studied. A three dimensional tire model is ...
  • Vibration characteristics measurement of beam-like structures using infrared thermography 
    Talai, S.M.; Desai, D.A.; Heyns, P.S. (Philippus Stephanus) (Elsevier, 2016-11)
    Infrared thermography (IRT) has matured and is now widely accepted as a condition monitoring tool where temperature is measured in a non-contact way. Since the late 1970s, it has been extensively used in vibrothermography ...
  • The viscosity of nanofluids : a review of the theoretical, empirical, and numerical models 
    Meyer, Josua P.; Adio, Saheed Adewale; Sharifpur, Mohsen; Nwosu, Paul N. (Routledge, 2016)
    The enhanced thermal characteristics of nanofluids have made it one of the most raplidly growing research areas in the last decade. Numerous researches have shown the merits of nanofluids in heat transfer equipment. ...
  • Viscosity of nanofluids based on an artificial intelligence model 
    Mehrabi, M.; Sharifpur, Mohsen; Meyer, Josua P. (Elsevier, 2013-04)
    By using an FCM-based Adaptive neuro-fuzzy inference system (FCM-ANFIS) and a set of experimental data, models were developed to predict the effective viscosity of nanofluids. The effective viscosity was selected as the ...
  • The wake of two side-by-side square cylinders 
    Alam, Md. Mahbub; Zhou, Y.; Wang, X.W. (Cambridge University Press, 2011-01)
    Aerodynamic interference between two cylinders involves most of the generic flow features associated with multiple structures, thus providing an excellent model for gaining physical insight into the wake of multiple ...
  • Wind barriers optimization for minimizing collector mirror soiling in a parabolic trough collector plant 
    Moghimi Ardekani, Mohammad; Ahmadi, Goodarz (Elsevier, 2018-09)
    Wind barriers, according to their sizes and shapes, can effectively control, shift and even modify the airflow field in their downstream. These structures can accelerate the wind flow over the mirror field and move the ...
